LOOM SHUTTLE-MOTION.

SPECIFICATION forming part of Letters Patent No. 266,361, dated October24, 1882.

Application filed December 19, 1879.

To all whom tt may concern Be it known that], JOHN GREENWAY, of the cityof Paterson, in the county of Passaic and State of New Jersey, haveinvented a new and useful Improvement in Loom Shuttle-Motions, of whichthe following is a specification.

This invention relates to that class of loom shuttle-motions known aspositive motions, wherein the shuttle employed is longer than the widthoftne cloth to be woven, and is drawn through the shed in the warps byfingers on each side of the warp, which alternately take their hold onthe shuttle when the latter is in its middle position-i. 0., between thesheds of the warp-and while one finger carries or draws the shuttle toits side of the warp, the other remains idle on the other side of thewarp until the shuttle is again delivered to it by the first finger. Theactuating mechanism and moving parts of the shuttle-motion are, with theexception of the shuttle itself, protected by a cover of metal or wood,preferably the latter, the curved side of which forms the inside guideof the raceway.

Figure I is a plan view of my invention with part of the cover removed,and Fig. II is a side elevation with the upper part of the mechanismshown in section in both figures, like parts being represented by thesame letters of reference.

Sis the shuttle, shown in Fig. 1 as in the center of its travel,provided with the recesses U and U for the ends of theactuating-fingers.

A and A are the shuttle-actuating fingers, provided with L-shaped slotsD and D.

O and O are the pivots or centers upon which said fingers vibrate.

R R is the raceway, struck from the center.

B is a T-headed lever, pivoted at E, and carrying at the extremities ofits arms the studs 0 H and H, which work in the slots D and D of thefingers A and A.

I is a connecting rod or link between the lever B and the lever L L,whose fulcrum is at M. The end L of this lever carries the roller P,which engages in the slot of the cam J on the shaft Q. By the rotationof shaftQ in the direction indicated by the arrow the lever LL, link I,and lever B will be caused to assume the positions indicated by thedotted lines, disengaging the stud H from the finger on the lefthandside, and carrying by the stud H the finger on the right-hand side tothe dotted-line position, the said finger carrying with it the shuttlebeyond the warps, where it remains until the reed has done its work ofbeating up the last weft-thread laid in front of it, and then theshuttle is again traversed through the warps by the reversemovement oflever B and fingers A A. The fingers, when idle. are held against thestops 1. and 1 in position ready to receive the shuttle on its return,by the springs Z'connecting the fingers.

\Vhat I claim is- 1. The combination of the supporting-frame and thestops tand t with the sh uttle-actuating fingers, spring Z, andmechanism for operating said fingers, substantially as shown, and forthe purpose described and set forth.

2. The combination of the lever B, link I,le- 7o ver L L,roller P, andcam J, with the actuating-fingers A A, arranged as and for the purposedescribed and set forth.

JOHN GREENWAY.
